Abstract

A device for the development of latent electrostatic images with the aid of a dispersion developer, in which the developer liquid is sprayed onto the exposed face of the image carrier by means of a slot nozzle or rows of holes, characterized by two hollow profile strips of at least the width of the image carrier, provided with one or more straight and through longitudinal grooves, and arranged parallel to each other at a small distance from each other, with the slots facing each other, and because in one of the two hollow profile strips are one or more slot nozzles or rows of holes extending over their entire length and which are arranged in such a way that, in the idle phase, the developer liquid protruding from the nozzles passes through the nozzle. slot or the grooves of the hollow profile strip, by the space between the hollow profile strips and by the slot or the opposite slots, to reach the inside of the slot. another hollow profile strip, while in the operating state, the excess of developer liquid not absorbed by the image carrier passes through the longitudinal slits between the nozzle or the nozzles and the slot or longitudinal slots, to reach the space which remains in the hollow profile strip around the nozzles, as well as by a reserve reservoir for the developer liquid and at least one delivery element of the usual type for the transfer of the developer liquid.
